I'm new on my first grow and ummm i didnt start flushing 2 weeks out. there ready to be harvested about in 5-7 days i'm guessing. Now i've used nothing but organic ferts and i've flushed these 5 gallon pots for 3 days now with nothing but water and sweetener. about 2 gallons each day per plant. Do i need to continue flushing daily before i harvest? Here's some pics before i started flushing. 2 on the left are opium and 2 on the right are WW.
